Differences in sexual size dimorphism among farmed tilapia species and strains undergoing genetic improvement for body weight
Type: Journal Article
Many tilapia (Oreochromis spp.) farmers produce all-male populations because of the superior growth rate of males compared to females. To investigate differences in body weight at harvest of males and females among different ...
Breeding plan for Nile tilapia (Oreochromis niloticus) in Indonesia: individual selection
Type: Report
The International Network on Genetics in Aquaculture (INGA) was established in 1993 with the objective to contribute through collaborative research, to the domestication and sustainable performance of tropical finfish ...
Genetically Improved Farmed Tilapia (GIFT)
Type: Brief
Genetic improvement through selective breeding has been used for millennia on crops and livestock, but up until the 1980s, little had been done to utilize this process for farmed fish. In response to the inadequate supply ...
Tilapia: The plain truth (Khmer version)
Type: Poster
This infographic is an overview of tilapia as a nutritious inexpensive and environmentally friendly food.
Performance of the Genetically Improved Farmed Tilapia (GIFT) strain over ten generations of selection in Malaysia
Type: Journal Article
A selection programme using Best Linear Unbiased Prediction (BLUP) method for the estimation of genetic merit was implemented by the Department of Fisheries Malaysia (DOF) in collaboration with the WorldFish Centre. This ...
Breeding plan for Nile tilapia (Oreochromis niloticus) in Vietnam: combined multi-trait selection
Type: Report
Total freshwater aquaculture production in Vietnam in 1995 was about 300 000 tons and total brackish water aquaculture production was about 115 000 tons. Total tilapia production was about 15 000 tons, mainly produced in ...
Genetic variance for uniformity of harvest weight in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Competition for resources is common in aquaculture, which inflates the variability of fish body weight. Selective breeding is one of the effective approaches that may enable a reduction of size variability (or increase in ...
Dissemination and evaluation of genetic improved tilapia species in Asia (DEGITA): final report (January 1998)
Type: Report
The major objectives of the DEGITA ( Project (Dissemination and Evaluation of Genetically Improved Tilapia Species in Asia) were: 1) to carry out genetic, socio economic and environmental evaluation of the improved tilapia ...
Genetic parameters for survival during the grow-out period in the GIFT strain of Nile tilapia (Oreochromis niloticus) and correlated response to selection for harvest weight
Type: Journal Article
The aims of this study were the estimation of genetic parameters for survival rate from tagging until harvest and the evaluation of the correlated response in survival rate to selection for harvest weight in the genetically ...
Closing the yield gap: improving production efficiency in smallholder farms of Nile tilapia through selective breeding
Type: Thesis
The aim of this thesis was to optimise the breeding program of Nile tilapia for a smallholder production system, thereby contributing to closing the yield gap. From Chapter 2 to 4, we generated information that can be used ...
